Swimming around in a mixture of language and matter, humans occupy a particular evolutionary niche mediated by something we call 'consciousness'. To Professor Nicholas Humphrey we're made up of "soul dust
": "a kind of theatre... an entertainment which we put on for ourselves inside our own heads." But just as that theatre is directed by the relationship between language and matter, it is also undermined by it
. It all depends how you think it.

More good stuff for people who like visual ("optical") illusions (previously
): A nice Scientific American article
, a particularly creepy
illusion, and a link
to the "Best visual illusion of the year" contest. Given that the eye/mind/brain is so easy to trick, a person might wonder what's really
out there in the world.

The McCollough effect
is a visual illusion somewhat similar to regular color aftereffects, but the working mechanism is different, and despite a wealth of theories
, not entirely explained. Once the effect is established, it does not seem to go away and can last for days or even weeks. Proceed at your own risk.

What's wrong with these pictures?
I thought I knew at least a little bit about art until I took this quiz. That, plus the blurb about spider-goats (eew!) makes me think that maybe decaf isn't strong enough to kick-start my brain this Friday morning.
